Tho apparatus shown in tho drawings is designvd to illustrate the host form or embodinn-nt. of our invention for uso in connection wit h u mnnhodv llHH'llllN of the typo having a running horn, like the machine covered by L0H ll'S Paton-2' No. 71 2 MN, hvlore mentioned, and in tonnm'iion with the descri )tion given lwiow :iitontinn is called in the following features, which distinguish ihis invention from othernnu-hinvsorupmmitusfor soldering the i sido swims of cans l Tlw soldenpot si'ts' in and is inolosed on. the sides and bottom by :i heating-trough,which, in :uldilinn to its ollii-e of kevping the solder in lluid state, has the function of a heater for ho soldering-irons. In this apparatus the soon: is soldr-rid on the inside Well as the outside of Th1 i-ulnhody hy an inside soldering-irozn and illl ulllside soldering-irons aeting jointly on the svznn as tho can-body is moved along hotwoen ilfl'lll, and the soldering-il'ons that operate on the seam from -the outside of the i-iunhody :1 re loosely suspended henonth the l1eating-lrough through a long 1 slot in its bottom in such manner that while the irons are free to play perpenilicularlv in 1 devices for applying the ltux to the joint the slot their weight is -iarried entirely h the trough and t ey do not throw any weir it on the stationary gnidednu' beneath, on which the can-bodies are supporteitl and presented to these outside irons. This roost ruetion by which the outside irons are carried by the heating-trough allows the sole of the outside iron to touch or set in working contact with the top bar oi the can-body guide without requiring that bar to carry the weight of the outside soldering-irons except during, the time a can-body is passing between the out-- side iron and the top bar, and consmpici'itlv the top bar of the guide can be relatively thin or narrow, and being composed of a considcrably smaller mass of metal than the outside iron it will be heated. by frequent contact with the outside irons in the intervals between the traveling can-bodies to a sullicient degree to give the top bar the operation or function of an inside soldering-iron.

The stationary can-body guide is supporl ed by the traveling carriers that move the can-body along through the soldering appa ratus, and the construction of this part of th apparatus contains several novel features, in

which provision is made For su iporting the can-body guide in position with relation to the soldering-irons and for moving; the can bodies as they come from the forming-machine at regular intervals apart. This part of the invention consists ClIIBfl) in supporting the can-body guide directly by the endless traveling carriers, which are constructed and su ported to attain that end, as more particular y described hereinafter.

Another novel feature is the manner of applyin the solder to the seam by feeding or 1Ilt!O( ucing it through the soldering-iron at a point behind the leading end of the iron instead of in advance of the point where the soldering-iron first comes in contact with the seam, the result of which is to heat the metal of the canbod v at or in the region of the joint before the solder is applied to it, and thus in sure a smooth and continuous flow of the sol der along the scam. Thi Feature of the iu vontion embraces also the novel manner of applying the solder for the joint both on. the inside and the outside of the seam without excessive waste during the movement of the can-body along the guide, to which end it con-- sists in feeding the solder into a chamber in the first soldering-iron, from which an outletassage leading out through the sole of the iron distributes the solder into the sean'i in the outside of the can-body and also deposits 3, small quantity of solder at regular intervals in a cavity in the top face of the inside stationary solderin -iron, from which a sulficient quantity is ta on up by the moving canbodv to finish the seam on the inside as it travels along the stationary iron.

Other novel features are embraced in the and on the wipers l'or finishing the seam both on the inside and the outside oi the calrliody.

The device vfor applying the lltlX has the form ol an oscillating finger supported over a trough into which the free end ol' the linger drops by gravity and ,l lfilli which it is raised by cuoh l'tl'lhlltltl) as the latt r moves along under the linger or between it and the trough. 'lhese parts are situated in. such relation to moth other and to thestationar) elm-support lug bar that the min-bodies onoireliur and passing: over the thavtrough and under the linger will tilt it from the trough and cause the end ot' the linger to ride on the scam, the intervals between one can-body and the next beingsul'licient to allow the finger to drop into the thin-trough and take up a fresh quantity of flux for the following can. The end of the liner-r is grooved or slitted For the purpose of takingup and retaining a greater tpiantitv ol the liquid than a solid end will taho up when alternately di )ped into and vritlulrawn l lulll the liquid in the trough.

The novel l'eatoros in connection with the wipers comprise a flexible wiper conipi'ised of several folds or layers of coarse fabric, sucl'i as canvas, fixed in. a clamp, and a pivotaltw set frame held in working contact and with sull'icieut degree of pressure against the canbody by a spring. The clamp is dcta-chably secured to the frame, so that the wiper when worn or burned on thoedges can he uioklyde-- tached from the trains and re ilaoei by a new wiper without interrupting t e operation of the machine.

The invention embraces other no' el features with respect to the means that support the can-bodies and carry them along through and under the several working parts of the apparatus, in the construction of which pro vision is made for adjusting the apparatus to handle and operate on dillerent sizes of can bodies as the forming-machine from which the are delivered to the soldering a iparatus is adjusted to turn out a can-body 0i another size.

The heating-trough u is supported in the rear of and above the horn 3 of the can-forrning machine by standards 5, secured at their lower ends 6 to a stationary bracket 4 and at their upper ends to the sides of the trough. The bracket is bolted to the stationary frame of the bm'lpforming machine, from the rear end of which the body-forming horn 3 extendsv The stationary guide g and the traveling endless carriers lb, that move the can-bodies along the guides, are adjustable vertically l) the following means: A stationary tracformed of a single casting 7, with a channel 8 ru nning longitudinally through. its center and with elevated sides provided with guideways 9, having planed top faces, forms a stationary track for the endless tra ve'line carrier.

tached upright bars 16 with s The casting 7 is supported by a slide to, illl ted to stationary guides 12 and adjuslahle vertically by an elevating-screw 13. A hear- 1 ing 14 between the guides and also It threuded socket 15 on the slide are provided for the i screw 13, and a hand-wheel on the lower end of the screw furnishes means for turning it. 4 At the end of the channeled ieee 7 are atl lots for. screws 17, by which the bars are fastened to the Siik I tionar support 4. The bars it) serve to support t 1e channeled piece 7 at the outer ends and hold it stiifly after adjustment At the 1 ends of this part 7 are sprocket-wheels 1S 1.) for carrying and giving motion to the endless l carriers. One of these wheels connected by a pulley 20 and a belt 21 with some shaft or revolving part on the lmdy-forming nor-- 5 chine, from which continuous motion is given l to the traveling carrier.

The parts It, termed the carriers, are blocks or projections provided with laterally extending arn'is 22, connected together ail intervals apart in an endless chain formed h links 23. These traveling carriers, in udi I it ion totheir work of moving the can-bod along the stationary guide, also support and hold the can-bodyguidestiffl in the required horizontal position, especial y that portion or lllti'l'llwI of the guide which forms the inside solderingiron. This inside support; for the van-bodies must necessarily be separate. and independent of the soldering-irons that operate on the outside of the can-bodies in order that the cans may pass between them. Owing to the length of this guide and the weight it is culled upon to bear additional supports lu-u'oud the end where the guide joins the horn fl are required. For this purpose the trawling end less carrier and the stationary traelr 7 :H'T' g constructed in the following manner:

The carrier-blocks h are slotted to lake in the bar g of the can-body guide and to slide smoothly along the bar without hinding, thus formin cradles in which the bar 9 is maintained in position and prevented from turning with the horn 3 of the forming-mu.- chinev The slotted earriirs thus have the double function of moving the can-bodies along, the can-body guide and of supporting and holding the guide itself stiflly and in line .with the soldering-irons. The slotted carriers h are in turn kept in line and supported under the weight of the load by the stationary track on which the arms travel.

The means provided for setting up the channeled bar 7 to adjust the (.lllldHHl)" guide withrelation to the soles of the solderingirons enables the contact and pressure of the irons on the seam to be regulated to the required degree simply by loosening the slot 1 ed r bars at the ends and raising or lowering the slide 10.

f g of the can-hotly The principal bars in thickness A guides are of such dimensions and ar set in such iclui row to the end of the horn it of the bodvl'orming machine that they are included within a r-irele corresponding to the internal dimensions of the eanbody. Additional guides of dill'ereul sizes are provided Wili'l'l' the euud'ormiug nun-lune is adopted by :uljustmeni to turn out (imbodies of different diameters, in which case one eondmdy guide is removed and another of the required size is sl'dislil utud. This part. of the uppers: us is at inched to the end of the horn Tl by a yoke 24, having it socket in line with the axis f the horn 3 to take a cen ter pin 25, fixed on tliecnd of the horn. The ion er memher g of the guide, extending from the yoke to the outer end of-tlie endless trav- Pllllll carriers from which the s ldered can hod 'is urn diseluirged, is ii continuous bar having for 21 support at the inner end the horn 3 and at soverul points in its length support ed by the slot led carriers 7;. her of the guide is eoinposml in part of two narrow liars] from the horn I; to :ho ildjll eeni end of the lending solderingiron, and from ilnil point to tlufurther end ol the lust solderiugiron the. nnrrow burflorms the reniaiuing portion.

Bel-ween lln liottoni bur g and the double. luirf space is provided for setting the trough s, eonlziining the flux, and the bars f are separated at sidl eient distunee for the end of the pivoted linger t to drop between them into the trough. The b ttom her 9 is cut away helow the hurf, us iudieuted in Figs. l and thereby forming shoulders or shut merits 2t}, lit-tween which is mounted ii lluxtrougli.

The linger i. is 2 llwruelclv lifted out of the t rough to ride on the top of the moving can boil; in; the latter is carried along and is reused to drop int-i the liquid contained in the i'lux-trough by gravity. 'lhe end of the linger is grooved or slitted from the point lnu-luvnrd, as seen at (it), lug. by virtue of which it takes up and retains u greater and n more uniform quantity of liquid than it. otherwise would do.

The single barf. Forming the reuuiining portion of the top member of the guide is supported from the bottom lruir l bracketpieces 12.). The side rails /r are used mainly for the purposoof insuring the continual ulinemcnt of the side SUtilllW/Vlllll the top bar tllHl keeping it in the groove 3U of the her.

As the lnireoutuius a smaller uniss of metal than the soldering-irons d above it and is in contact with one or more of the irons at all times, it becomes hented quickly, and its tenlpernlure is nnvi ituined sullieiently high to give the bur the function of an inside soldering-iron 'lhe scum thus is finished on the inside as well as the outside of [he eunbody.

vln the niodifimtion illustrated in the crosssei'tion, Fig. 8, two sets of traveling carriers are arranged on opposltc sides of tin chunnol l solder to this S'I'l'tlll in rhnrgt-sof definite quanto support the (um-guide and also to (have tity is :tnovel und valuahlel'ceture oi thisinthe cine-bodies from the side instead of from honra'ith. 'lhc hitcriilly-extelidiln; roll of thrrun-body guide in this construction is formed of a single bar 32, corresponding in width to the internal diameter of the (.2Hl-l)('llll9fi, or approximately so, and to this bur is rigidly secured the top burfund the bottom llill g by angle-irons 33.

The upright sidcs oi the channeled piece 7 have grooves 27, in which the slotted carrierblocks h are fitted to slide smoothly, and

behind the groovrs are IHUFQSHS 26 for tho links that connect the blocks together in an endless belt. Sprocketwheels at the op positc ends of the channeled support '7 mountcd'in brackets 29 to rotate in hori 1,o11- tal planes and are properly colmrcted with a driving-shaft to have continuous motion with like rate of spend. This um nner oi sup-- porting tho cam-body guid and driving thrcau bodics from the slots instead of from the lower edge alone is of advantage in securing: a uniform and stcndy inot ro and a. true horizontzil position of the run-body guide, pair ticuhirly in operating on con-bodies of thrlarger sizes.

The troughnis utilized to heat the solden lug-irons as well as to keep the solder in u. fluid condition for the work. Burners oi" uny well-known type can be employed for tho heating agent located at the side it the trough in line with openings .30, through which the flames and gases arc directed into the incloscd space around thc sides of the solder "'csscl b and also in the space under the bottom, which forms the heeting-chnmh r for the outside soldering-irons.

The lust-mentioned irons are suspendrd from the inside of the trough through it slot 34 in the bottom, with the heads of the irons standing above the bottom of the trough and the tips touching the barf of the elm-guide. The irons are loosely hung in the slot by means of cross-pins 35, that prevent them from dropping through thi slot and at the same time allow a sulficicut extent of vcrl ll'lltl play in the slot for the iron to he lifted and Ede on the seam as the cen-body runs under the irons. These outside irons (Z and tho bar f should he 30 adjusted witlrrclation to catch other that the sole of the iron makes contact with the top barf sufficiently close to-conduct the heat to the barf without throwing the whole weight of the irons on tho barf, and the contact is regulated and controlled by the means n'ovided for Vertically adjusting the oan-bo y guide, of which the inside soldering" iron is a menber. Each iron is formed of a solid block with the sides beveled to reduce the same at the bottom to a narrow solo or acting face of about the same width as the seam.

The means for feeding and applying the wuntion, hiefly in the uniform murmur in which the uprmrntus controls and distributors the quantity oi solder required to close the swim with it minimum of waste. This funluru oi the in vention consists in feeding the soldor from the solder-pot to u recess or rhumhcr in tho soldcringdron in drops, the size and the frequency of which are under the control of the operator, and in conducting and distributing the solder along the seiun frou'i end to and through. an outlct-passage opening through the bottom of the iron. The soldur is applied in this manner by the foremost or leading soldering-iron with which the cecu hody lirst comes in Contact utter it pas." as through the fluxiugdcvice, and in the construction of this part of the Ttppuruins the foremost soldering-iron 07" has a, tuliuhtr possugc 1m extending from the head iorpuudiruhirly through the bottom time.

A trod-tube fixed in an outlet 39 in thc bottom of the solder-pot b above the iron, extends perpendicular down into'this passage in the iron, and being somewhat smaller 1n diameter than the passage, so as to fit looselv in it, the tulirhits a contracted lower en with rm outloteaperturc 40, through which the solder escapes in drops into the passage through the iron. The dischar of the solder from tho solder-pot through this tube is con trolled and regulated by a. valve formed of a pin -11 having a cylindricalupper portion of the some din motor as the outlet-a. )e'rt ure in the hottom of the solder-pot; but lower portum lying principally within the passage in the tu be 38 ull orids space around the pin for the solder. The pin is cut away or flattened on the sidr, as soon at 42, to afford an outlet of sulliiiient urea. from the solder-pot into the pi ego, and its lower end terminates in a pin 14, shaped to it the outlet 40 at the bottom of the passage. it has it screw-thread 45 near tho upper end, working in a. threaded hearing 46, for raising and lowering the vulvc.

The area of the outlet in the end. of the passage is varied by sorouing the vulvo up or down, which is udil'y done by :t he or a n5 screw-driver applied to the head of 1.- 16 pin 41, thus allowing thel'es d to here nlotod as the work may seem to requirennr. to be out of? altogether when calhbodies are not running through the apparatus. When the pin scrcweiil down, the stem 44 fits in and closes the outlctnporturc 40, and by moving the pin u and down the outlet is readily cleaned wicnever it becomes choked. By virtue of this construction the solder is supplied from a body or mass of the molten metal with a minimum Waste, where the 013mhodies necessarily follow one another at in- -tervals in a continuousimenner frontthccam ticularly that tho llollom loco of tho lllltfiilll .lI'Oll rests upon the insirio S(Jl(l(lllli-ll'l il mm with the outlct-apvrturc 7U ilirci-lly o i'i-r the: cavity 30 in the iusiilr' iron so that lioili arts of the seam are suppliod with sol lvr 'rom thc same sourco tilt'l on: under control through the some valro. 'llmt portion oi the solder-dealing tulm which is (-xposml to the heat from tho burners is proti-ctul by :1. sleeve 48, resting at tho lmwr and on the. head of tho soldcriug-iron mid loosclj' lilting the nook around tho uponing I?!) in tho bot-- tom of the sol loringrrougli, that it may move pr rponclicularly Wl t h the soldcri':i;,;--iron. These parts, necessarily lacing usposwl to great heat continuously (luring tho i'rpPl'Flllllli of the apparatus and roquirin r to ill rvnowod from time to time, on. dotuo'mblo loam inc. trough.

Similar provision is lnaclo with the Wipers that pm'lorn] the final o; r u on of finishing the outside and tho inside: f the seam, as these ports also come into hontsct with the heated surfaces to such an sxtcnt as to materially reduce their e'llioicucy in a short time.

The set of wipi rs 50, that act on the scam from the inside of the mm, are hinged to tho stationary bottom bar 9 of tho con unis, and each Wiper is pressed upward against the. can-body by a stiff spring 55. The outsids wipers are attached to a bracket 54} by a n e-joint 51 in the sums nisnn soil the b0 y of the wi 'lers in both sets is torn .d of coarse cloth, such as canvas, is folds or layers of several thicl-incsscs tightly messed together in the form of a pad and fustcncd to the hlIIgPdlUHI: so as to present the front edge across tho seam. A flexible Wiper of this character readily bcndin and conforming to the curved surfsccs o. the ClldlrhOflY,

both on the outside and inside, removes all excess of solder l'rom the surfacss and produces a clear and smooth oint; but owing to the liability of becoming charred by the heitted surfaces with which it comes in contact, provision is made for setting up the acting edge of the pad, as well as for rsucwing the pad Whenever it has become charred or otherwise affected by the heat suflicicutly to reduce its serviceability.

The outside wipers can be adjusted by the bracket 54, that carries them, and that art being secured to the stationary frame y a clamp-screw 56, it can be lowered from time to time as tho wipers need setting more closely to the scam without intcrrup ting the operation of the apparatus. The inside wipers being supported from the stationary guide over which the can-bodies travel are i not so readily adjusted, and a construction of detachable pad that can. be rr-inovod when too badly worn and quickly replaced by a, new wifiier is ro'vided for application more cspecia y to t e insidewipers, although the lust mcniiouvd is shown in Figs. ll) and 11..
